Here's the Slate link. Here's the Deadspin link.
...With proposed rule changes like these, I ask myself, "What if things had always been this way? Would we want to change from that to the way things are now?" If football didn't have the extra point—an odd play that's meaningless to game outcomes 99.9 percent of the time—would we want to invent one? Probably not.
In this case, if we'd always started the game with a punt, would we want to invent the kickoff? It's not so clear. With the yard line of the kickoff now at the 35 and as placekickers continue their trend of booting the ball farther, it won't be long before every kickoff is a touchback. The kickoff might soon become like the extra point—a boring formality...
I strongly recommend Keith's post on the subject too.
